Sound and audiovisual training

Exploration of sound and audiovisual training according to Anadi Martel

Introduction :

The exploration of brain capabilities through sound and audiovisual training has seen significant developments over time. In her book The Power of Light, Anadi Martel shares observations and experiences on these two fascinating methods. This article will look at sound entrainment, with an emphasis on the use of pulsed tones and binaural waves, as well as audiovisual entrainment, an approach that combines visual and sound stimulation.

  1. Sound training:
  • Principle of binaural training:

The most common form of sound entrainment, known as binaural entrainment, relies on the simultaneous presentation of two tones at slightly different frequencies to each ear. This method, discovered in 1839 by Heinrich Wilhelm Dove , generates low-frequency beats that influence brain waves. Studies, notably those of Robert Monroe, have highlighted its potential in exploring altered states of consciousness.

  • Effectiveness compared with visual training:

Anadi Martel points out that after experiencing both forms of brain training, visual training turns out to be more effective than auditory. Clinical research conducted by Frederick and colleagues in 1999 confirms this observation, demonstrating that visual training has an effect approximately twice as pronounced as its auditory counterpart.

  1. Audiovisual training (EAV):
  • Simultaneity of stimulations:

Audiovisual training (AVT) combines simultaneous visual and audio stimulation. Since the 1970s, EAV devices, often glasses equipped with pulsing lights and headphones, have been developed to exploit this synergy between the two senses.

  • Technological evolution and limits:
    Although generations of EAV devices have emerged, some recent studies question the effectiveness of binaural technique in inducing evoked potentials. This questioning highlights the fluidity of research in this area.
  1. Exploring resonance:
  • Importance of resonance:

Anadi Martel emphasizes the importance of resonance in her own research. Brain waves, measured using instruments such as the Mind Mirror, have been crucial in assessing the impact of sensory stimulation on consciousness.

  • Resonance and technology:

The author discusses the Mind Mirror, a revolutionary instrument from the 1980s, emphasizing its simplicity and clarity for synthetically visualizing the mental state. Although more complex devices exist today, the Mind Mirror was a valuable tool for his initial studies of EAV.

Conclusion :

Exploring sound and audiovisual training offers a fascinating look into the brain's capabilities. Anadi Martel's work, based on concrete experiences and studies, invites us to reflect on the potential of these methods to improve consciousness and explore modified states of it.
